- Manage Enterprise Data Flow: Oversee data pipeline integrity and real-time data flows between core applications and external downstream systems to ensure zero data loss.
- Drive Innovation via PoCs: Execute agile Proof of Concept (PoC) initiatives to validate integration approaches, assess structural feasibility, and demonstrate technical capability to client teams.
- Act as a Strategic Feedback Bridge: Serve as a key representative to the client while collaborating with global internal engineering and product management teams to share regional product feedback continuously, strengths, and upgrade strategies.
Requirements
- Bilingual Capabilities: Native/Fluent Japanese (JLPT N1 level or equivalent) with a deep grasp of Japanese business practices, paired with professional English skills (TOEIC 700+ or equivalent) for internal global engineering alignment.
- Proven Track Record: 7+ years of combined experience spanning hands-on software development and professional IT consulting (with a minimum of 3 years dedicated to each domain).
- End-to-End Delivery Leadership: Demonstrated success acting as a technical lead for large-scale enterprise deployments, managing the complete lifecycle from requirements gathering and architecture design to code reviews, testing, and production release.
